The 15 kA (EN 60898) and 25 kA (IEC 60947-2) ratings cover most industrial panel fault levels; the higher IEC figure applies when the MCB is used as a distribution breaker per 60947-2. At DC, it breaks 15 kA at 60 V, with a maximum DC operating voltage of 72 V. The IP20 rating means it is protected against solid objects over 12 mm (fingers) but not against moisture; install inside a sealed enclosure if washdown or condensation is present. Ambient temperature derating applies per: full rated current up to 55 °C at 95% humidity, then derate to 55% at 70 °C and 35% at 75 °C.
Rated for mechanical engineering and industry, this MCB protects branch circuits in control panels, motor control centers, and distribution boards. The B-curve makes it a good fit for resistive loads, lighting, and small motor circuits where the inrush is under 5× rated current. The halogen-free and silicon-free construction is relevant for environments sensitive to outgassing — clean rooms, food processing, or aerospace-adjacent panels.
